Who Shepherds the Sheepdogs?

DellCon#36 and I'm being introduced to the boardgame Caverna.  This is by the same designer (Uwe Rosenberg) and very much in the same mould as the predecessor farming game Agricola.  In this case the 'farm' development is set in caveman times.

I'd generally picked up that Caverna was supposedly so much the better game of the two.  Hmmm - not convinced.  Suffers, in my opinion, the exact same issues of some of his other games - that someone who knows the cards/tiles and the optimal mixes of them, will wipe the floor with an occasional player.  OK, so now I know how the mop feels.
